Many people on social media, and in our office, are reporting that the update process didn't go as smoothly as it has in years past.

Apple confirmed the issue in a statement provided to Business Insider, and says the problem has been resolved:

"We experienced a brief issue with the software update process, affecting a small number of users during the first hour of availability. The problem was quickly resolved and we apologize to those customers. Anyone who was affected should connect to iTunes to complete the update or contact AppleCare for help."

Several iPhone users have told me that the iOS 10 update is asking them to plug their phones into iTunes.

If you update your phone and you're not by a computer, that means you might not be able to use your phone until you find a desktop running iTunes.

One user told me that his phone gave him only two options when he plugged it in — "update" and "restore." The top image is an example of how his installation went wrong.

But once your phone is plugged into a computer running iTunes, the update goes mostly smoothly — and it won't erase your data. Here's Apple's advice:

If you still see the Connect to iTunes screen after you restart, you need to reinstall iOS:

Connect your device to your computer using the cable that came with your device. You should see this message: "The software on [your device name] needs to be restored to factory settings or updated."
